So after spending quite a bit of money on toys for a 1-year-old long-haired dachshund because she's a very aggressive chewer I took a chance and bought this rope set and it's been 2 months she still has all her ropes everything I must say this is a very durable set well worth the money well worth the play time she loves tug of war these ropes are great for tug of war she has not chewed through any of them she has tried to take them apart which she had succeeded on one but I put a few knots in it and other than that I would recommend this rope set to anyone that's got a dog that likes the fat especially play tug of war or is a very very aggressive sure

Doggos are excited but...

Size: Large, Color: 9 Packs

My dogs are ecstatic about their new ropes. But they're big and aggressive chewers. These ropes are thinner than the pictures made them look. I'd say they're appropriately sized for dogs up to 35 lbs - and not as great for the large breeds show in the pictures.

Dogs love them.

Size: Large, Color: 6 Packs

My dog loves playing with these toys. I also bought some for my daughter‘s dogs. They really love them. I would say the only downfall is that they shred easily. You’ll find little strips of yarn laying around. But that doesn’t bother me because they get a lot of enjoyment from them. I have bought them three different times.

My Dogs Fought Over These!

Size: Large, Color: 6 Packs, Size: Large, Color: 6 Packs

Pack of 6. I specifically ordered a pack of them so each dog would have their own. They still fought over them. lol I only see two of them now because they have hid them from each other. So far, they are holding up well. Heavy enough to toss to them but light enough not to hurt them. Loved the variety of colors. Only issue I have is they are a little small for my mastiff but still giving it 5 stars because the ad stated it was for medium dogs.
